The purpose of this study was to determine the effect of dietary vitamin E reduction on blood cholesterol levels (LDL and total cholesterol). Eight healthy older adults between the ages of 40 and 60 volunteers were used for the study. Subjects acted as their own controls during the two week baseline period in which they ate their normal diet and kept precise diet records [three day diet recalls which were analyzed for vitamin E content using the Diet Analysis program (Food Processor version 8)]. A vitamin E reduction diet was created for each individual using the same Diet Analysis program. This vitamin E reduction diet was designed to significantly reduce the amount of dietary vitamin E intake of each subject while keeping calories relatively similar throughout a period of three weeks. Fasting blood draws and three day diet recalls were collected every week. Vitamin E intake, total calories, HDL, LDL, TG, and glucose values over the course of this study were compared with a one-way ANOVA using repeated measures. Post-hoc testing using Duncan and Scheffe comparisons were made to indicate any statistically significant difference. Significance was set at p<0.05 and all values were reported as x ± SEM. The averaged three day vitamin E intake was reduced by 55% (20.3 ± 2.6 mg to 11.2 ± 2.1 mg). There was no significant change in total cholesterol, LDL, HDL, or triglycerides from baseline to the conclusion of the study.The results suggest that short term reduction of dietary vitamin E has no effect on total or LDL cholesterol. / School of Physical Education

This investigation, comprising two studies, examined the number of barriers to physical activity (Study 1) and barrier strength (Study 2) reported by middle-aged and older adults using a social ecological framework (McLeroy et al., 1988). Researchers were interested in assessing age group (45-54; 55-64; 65-74 yrs) by physical activity group (active, less active) effects for barrier responses using analyses of variance. In Study 1, 180 participants completed a physical activity level survey (Godin & Shephard, 1985) and answered open-ended questions about barriers. Results indicated that 45-54 yr-olds reported more barriers overall, and more intrapersonal barriers than older groups. Less active 45-54 yr-olds reported more organizational-interpersonal barriers than the other groups. Descriptive analyses of coded themes demonstrated that common intrapersonal barrier sub-themes cited by younger adults related to family commitments, while sub-themes reported by middle-aged and older adults related to having a health problem or an injury. In the organizational-interpersonal category, the most common barrier sub-theme related to the workplace. In Study 2, 116 participants completed a survey assessing weekly physical activity and barrier strength for items pertaining to ecological categories and barrier sub-factors. Results showed that less active adults reported each of intrapersonal, interpersonal, and physical environment barriers more strongly than active adults, irrespective of age; the intrapersonal category was relatively the most constraining for our participants. In terms of barrier sub-factors, results showed that significantly higher barrier strength scores are most often associated with physical activity level (i.e., less active), and only occasionally associated with age group. The overall investigation can provide valuable information for improving physical activity interventions for middle-aged and older adults.

Lifespan developmental theory suggests that midlife is an important stage where men typically re-evaluate major areas of their life including career, self/masculine identity and primary relationships. Midlife is also seen as a period where the desire to pass on what one has learned, or regeneration, becomes important. These aspects of midlife can be looked at from several perspectives including Jung's theory of personality type which has since been interpreted and extended by Katherine Briggs and Isabel Myers to form the basis of the Myers-Briggs Type Inventory. It can be concluded that personality type does impact on the male midlife experience and thus has implications for counsellors working with men in midlife. / Thesis (PhD)--University of South Australia, 2006.
